I have found no way whatsoever to reduce contraband, I have 300+ pieces while I'm doing a shakedown a lot of the time, it never really seems to go down, even with dogs and metal detectors all over the prison. Tunnels are another issue, the dogs detect them, a flag is placed, I'll do a shakedown and the guards won't find it, and I have to wait for a prisoner to escape to find the tunnel. Anyone got any tips on what I can do differently/better?
